Specification of Letters Patent.

raten/ced March 24, i908,

` Application led November 10, 1904. Y Serial No. 232,115.

To all whom it may concern.'

Be it known that I, WILLIAM F. HAUSS- TEIN, a citizen of thc UnitedStates, residing at Lyndhurst,'in the county of Bergen and State of NewJersey, have invented certain new and useful Improvements inCalculating- Machines, of which the following is a speci ication.

. operative position and the invention con` -This invention relates tocalculating Inachines, such as that which. forms the-subject matter of'U. S. Patent to Alexander Rechnitzer, Number 809,075, granted January 8,

In that machine the operations of addition, subtraction, multiplicationand division are performed andthe ,machine in order to warn the operatorwhen the calculating machinery is not in. properpositionto beoperated,^has an indlcator which displays at the proper and impropertimes for starting the machine appropriate legends, as for instance thewords Right and "Wrong respectively. Notwithstanding this warninghowever, there is danger that the operator may overlook it and start ,upthe machine lwhen the word "Wrong is displayed and thus break ordisarrange many working parts.

The object of this invention is to make it impossible to start themachine unless the word Right is displayed by the indicator showing thatall of theV parts are in correct sists in providing such a machine withmechanism for carrying out this object.

'In the accompanying drawings, in which I have' illustrated themechanism comprised in this invention and so much of the original'gmachine as is necessary to properly disclose the constructiony andoperation of the various parts, Figure 1 is a top plan View, parts beingshown broken away, parts being 1n dotted lines, and the starting'leverbeing in section. Fig.' 2 is a transverse vertical section on a plane tothe right of the locking bar and starting lever looking to the right.Fig. 3 is a front elevation, the front of the casing being removed andparts being broken away. Fig. 4 is a top plan view of the locking barand connecting parts, parts being omitted and others broken away, thelocking bar being in unlocked position, and Fig. 5 is a similar Viewwith the locking bar in locked position.

ln`the"original machine a casing incloses the parts, of which the topplate is shown -at l and said top plateis provided with alongitudinalslot 7 having two forwardly eXtend- I ing 'lateral branchslots 8 and 9 and end spaces 10 and l1. A starting lever 12l is securedto a shaft 13 journaled in bearings 1--1 secured to the baseoi:` themachine. This starting lever which projects upwardy through the slot 7,will start the maclnne toperform the operation of .addition when movedinto the branch slot V8, subtraction when moved into the branch slot 9,multiplication when moved intothe end space 10, `vand division whenmoved into the end space 11.v In the original machine vthere alsoyappears a shaft 15 carrying a suitable number ofjnumeral' wheels, as at16, said shaftbeinv connected with another shaft 17-,by' suitablegearing 18 and provided with a segment 19 bearing the words Right andWrong to indicate through a suitable sight hole 20, (Fig. 1,)

the positions of the various moving parts of positions are indicated bythe exposure ofthe word Right. f

,f In carrying out' the objectof this invention, the mechanism'which Ishall now describe has been added. On the shaft 15, which carries thenumeral wheels and indicating segment, is secured a crank 'armv 21carrylng a wrist pin 22 which enters a curved slot 23 in an arm 24secured on a shaft 25 whichshaft also carries a iinger 26. On thestarting lever shaft 13 is secured a locking plate 27 provided withnotches 28 in its outer edge, to coperate with a locking bar 29slidablysecur'ed to the base of the machine by screws 30 passingthrough. slots 31 into the base. At that end of the locking bar in linewith the finger 26 there is provided a recess 32 having an inclinedwall'33l and at the opposite end, said bar is provided withan Aupwardlyprojecting lug 34 having a for- Wardly projecting tooth 35 at its to anda spline 36 on the underside of said toot 1. The locking arm isynormally held in inoperative position by a spring 37'.

The indicating mechanism and all of the parts on the shafts 15 and 25 toand including the finger 26 are mounted in the sliding carriage 38 whichis provided with wheels, or rollers 39, resting upon the base of the1nachine, while the starting lever, its shaft and allattached parts areon the stationary base Ytion shown in dotted lines in Fig. 2.

of the machine. In order to start 'the inachine, the starting lever musteither be rocked, with its shaft, to bring it into one of the lateralbranch slots S or Q, or it must `be moved longitudinally of the machine,(With its shaft) to bring it into one of the end spaces l() or'll` When'the shaft 15 and its numeral Wheels are in correct position (whichWould indicate that all connecting parts were also in correct position)the crank arm (Fig. Would depend substantially vertically and its Wristpin 22 would be in the center of the curved` slot 23 in the arm 2acausing the segment 19 to show up the Word "Right in the sight hole 2()and the finger 26 to assume the posif ln this position this finger, atthe end of the sliding movement of the carriage would pass into therecess 32 of the locking bn 29 and the machine would bc started foranother operation by either rocking or sliding the starting lever, asbefore described. Should, however, the parts at any time get into aWrong position, the shaft 15 ivill be turned to show Vrong in the sighthole (F ig. l) the Wrist pin on the crank arm 2l would move toward oneend of the curved slot (Fig. 2 full lines) and the fmger 26 be moved tot-he full line position of Fig. 2. In this position as the carriage isreaching the end of its travel the said pin Will strike the inclinedWall 33 of the recess 32 in the locking bar 29 and cause the bar'to moveinto a locking position With the tooth 35 overlapping the locking bar-27thus preventing the starting of the machine to add or subtract byrocking the starting lever. The spline 36 engaging in one of the notches28 of the locking block 27 alsouprevents the starting of the machine tomultiply or divide by preventing the sliding of the starting lever Withthe shaft 15.

Thus it will be seen that not only Will the operator be warned by thedisplay of the Word Wrong on the indicating segment, buttlie startinglever Will be rigidly locked to prevent the starting of any newoperation.

Then the vvordmlVrong7 shows up, the' numeral Wheel shaft may be turnedto zero by the means provided in the old machine, which will shift theparts so as to display the Word Right and to bring the linger 26 intooperative position as before described.

From an inspect-ion of Fig. it will be seen that the Wrist pin 22 willshift the hnger 26 to the Wrong or operative position when said Wrist inis moved from the center to either end o the curved slot 23, thuslocking the machine when the numeral wheel shaft is displaced orslightly Wrong in either direction, the segmentdisplaying Wrong .throughthe sight hole in either displacement.

What I claim as new is:-A
